1, winter solstice, also known as solstice, winter festival, sub-year, etc. It has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk ancestor worship festival in China. The solstice in winter is one of the eight festivals in four seasons, and it is considered as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year. The custom of winter solstice varies in content or details due to different regions. In southern China, there are customs of offering sacrifices to ancestors and enjoying the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.

2. The winter solstice is the 22nd solar term in the "twenty-four solar terms", and the solar calendar reaches 270, which is celebrated every year in Gregorian calendar 65438+February 2 1-23. The solstice in winter is the extreme point of direct sunlight spreading to the south. From winter to the sun, the sun shines directly on the tropic of Capricorn, and the sun is most inclined to the northern hemisphere, and the elevation angle of the sun is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest. The solstice in winter is also the turning point when the direct point of the sun returns to the north. After this day, it went back, and the direct point of the sun began to move northward from the tropic of Capricorn, and the days in the northern hemisphere became longer day by day.

3. In winter solstice, although the sun is low and the days are short, the temperature from winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice. Because of the great difference in climate in different parts of China, this climatic winter is obviously late for most parts of China. The winter solstice marks the beginning of the cold season, and people begin to count nine to calculate the cold days.
